Dos cilindros coaxiales muy largos, uno macizo y otro hueco están cargados. El primero que tiene un radio de 2 cm y es un conductor cargado con una
carga por unidad de longitud de 9·10-9 C/m El hueco de radio interior 5 cm y
radio exterior 8 cm, está uniformemente cargado en todo su volumen con una
densidad -4/π·10-6 C/m3.
i. Determinar la expresión del campo eléctrico en las distintas regiones:
r<2, 2 ii. Representar el campo en función de la distancia radial
iii. Calcular la diferencia de potencial entre un punto situado en el eje y
otro situado a 15 cm del mismo, a lo largo de la dirección radial.

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
